Some random drabble, CS/CC crossover (au) one-shot.
During their portal jumping, Emma and Mary-Margaret separate. Instead of being sent back to Storybrooke Emma has been sent back to the time when Hook was still Killian Jones. And much to her dismay, she will have no further choice but to seek alliance with him. If he is her only option of getting back to her time before time runs out, so be it. (Not good with summaries. :P)
" As David un-linked arms with her, and her hand took Neal's. Killian knew in that exact moment that he'd never be her's. And she'd never be his."
